chore(poc): test actions-package-update GH action

[csouchet]

Covers #668

[csouchet]

ℹ️ I created a fix PR on the repository of the GH action, because there is a weird behaviour on how to set the token for Ocktopit: taichi/actions-package-update#38.
It may be explain the error on our workflow, because after checking the token, the token user rights on the repository, and the use of this token on other repositories, there is no reason to have no right to push the code on this repository.

I suggest finding alternatives to using this action.
Although it updates dependencies automatically, it does not provide any information about the changelog content. This is a major piece of information that helps decide whether or not to update a dependency, especially when there are no automatic tests, as here.

Notice that dependabot recently introduced a way to group dependency update: https://github.blog/changelog/2023-06-30-grouped-version-updates-for-dependabot-public-beta/

Done in #1041

As nothing happening in taichi/actions-package-update#38, and we use now the beta version of dependabot group feature, I close this PR.

Be free to reopen it, if there is something new.
